JESSE M. ROBINSON, OF ALAMEDA, CALIFORNIA.

REPEATING EXPLOSIVE TOY.

seaaoa.

To all wlw/1a it may concern:

Be it known that I, J'nssn M. ROBINSON, a citizen of the United States,residing at Alameda, in the county of Alameda and State of California,have invented new and useful lmprovements in Repeating Explosive Toys,of which the following is a specification.

This invention relates to that class or description of toy, which isdesigned to explode a cap, disk or wafer of fulminate composition, andgenerally known as dynamite canes.

The object of the invention is the production of a toy or device havinga magazine or chamber containing a number of caps or wafers and meansfor feeding them in succession to the exploding means, whereby thedevice is self-charging and is capable of firing one shot after anotherwith a greater or less frequency as desired without the necessity ofinserting an explosive cap or wafer for each shot.

A further object of the invention is to provide a simple and effectiveoperating repeating exploder for caps or wafers at relatively smallcostl of manufacture.

The nature of my said invention and the manner in which I proceed toconstruct, produce and carry out the same are explained in the followingdescription, wherein the accompanying drawing illustrating a repeatingexploder embodying the novel fea'- tures thereof are referred to byletters and figures.

Figure 1 is a general view of a repeating exploder of my inventionshowing the same fixed in the end of a cane or staff for use like theordina-ry dynamite cane. Fig. 2 is a vertical section on an enlargedscale taken through the middle of the magazine, Fig. 3 is a detail viewof the hammer.

The body of the exploder is so formed as to be readily cast in onepiece, being prefer ably a metal block with the exploding chamber 2 andthe magazine l side by side, separated by a wall 8 in which is formed atransversely extending slot 5. This slot 5 is both a connecting passagebetween the two chambers, through which the explosive caps aretransferred from the bottom of the magazine to the exploding chamber,and also a vent for the gases.

In the last-named chamber is the hammer l) composed of the plunger 6loosely fitting the chamber 2 so as to slide easily, anda head or massof metal 7 on the butt end on Specification of Letters Patent.

the outside designed for the double purpose of taking the force of theblow when it is struck against the ground and of increasing the impactof the plunger against the explosive which is inserted between theplunger and the anvil 9 at the top of the chamber.

The means for feeding or transforming the explosive caps CZ 'from themagazine to the exploding chamber comprises the feeding slide e fittedto move easily in the slot, and a yielding arm or lever preferablyformed of a flat spring attached to a fixed point 10 on the body a andpassed through a slot 18 in the feeding slide e. With this lixed pointof attachment for a fulcrum the part f on being pressed outward at thefree end operates to draw out the feeding slide a sufficient distance toclear the chamber of the magazine, and by virtue of its resiliency asthe pressure is removed, or the free end relieved therefrom, the part facts on the slide with the effect to throw it forward across t-hebottom` of the chamber. A stop 15 on the slide regulating the length ofthat movement prevents the end of the slide from projecting into theexploding chamber in the path of the plunger. Provision is made foroperating the slide in this way automatically from the strokes or motionof the firing-piece or hammer, and in the present construction the sameis effected in proper time with the movements of the plunger by soarranging or shaping the spring f that its free end will rest on or lienormally in close relation to the inclined edge of a projection 16 onthe plunger, the latter part being so arranged at a proper angle withrespect to the perpendicular motion of the plunger that it will give therequired length of outward throw or stroke to thc feeding slide i'n theexploding stroke of the plunger, as the head is struck or droppedagainst the ground. As thus constructed and arranged the feeding slideis thrown forward when the plunger drops at the moment that the exploderis raised from the ground after the explosion, and a fresh cap is setfrom the bottom of the pile in the magazine into the exploding chamberready for another shot.

In the upward movement of the plunger the cap in the recessed hammer endof the plunger is brought with force against the anvil 9 formed by theupper end of the exploding` chamber. At each explosion, therefore. thecam 16 moves upward and the feeding slide is set backward to take afresh cap from the magazine by means of the spring f, and on thedownward motion of the cam the slide is thrown forward to bring the capinto firing position. The communicating passage between the two chambersis closed by the plunger at the moment the explosion takes place,thereby shutting off the magazine chamber and eliminating all danger ofsetting oft' the caps in that chamber.

A vent 18 atv the top of the exploding .chamber affords outlet for thegenerated gases necessary to produce the desired noise.

For conveniently operating the exploder it is xed on the end of a stickor staff g; the body a being provided with a socket 19 .for thatpurpose, and with an intersecting hole 2O for a pin or screw to fastenthe stick g. Y

The caps CZ are confined in the magazine by a cap or stopper It, acoiled spring placed between the topmost cap in the pile and the stopperinsures the regular downward movement of the caps in position in frontof the feeding slide. Y

I claim:-

l. A repeating exploder, comprising a body having an exploding chamber,a reciprocating hammer arranged to operate therein throughan aperture inthe bottom, a magazine chamber contiguous to but separated from theexploding chamber by a dividing wall, having a communicating passageopening from one into the other and located at the bottom of theexploding chamber, a feeding slide movable in said passage and extendingoutside the body, and a spring connected to the body, loosely attachedto the feeding slide and bearing on a cam on the ring plunger to operatethe feeding slide from the movement of the tiring plunger.

9.. In a repeating exploder, the combination with the body having anexploding chamber, a magazine chamber contiguous thereto and acommunicating passage between said chambers; of a reciprocating firingplunger in the exploding chamber adapted to operate through the bottomthereof, a feeding slide arranged to move in said passage across thebottom of the magazine chamber, a cam on the firing plunger and a springconnecting the feeding slide with the cam to Operate said feeding slidefrom the movement of the firing plunger, substantially as set forth.
